Glass shared a few tips on how bosses can appear more powerful using body language:

1. Straighten your posture

Sitting up straight won't just make you look better in front of your employees. It'll actually boost your confidence — at least momentarily.

As WGN TV previously reported, a 2016 Northwestern University study has found that your posture is directly linked to your mood. Participants reported feeling happier and more powerful when they improved their posture.

2. Lean back

Writing for Forbes, Carol Kinsey Gorman lists leaning back as a classic "high-power pose." When you lean back, you don't just project power — striking this power pose will also release higher levels of testosterone.

3. Put your hands in a steeple position

Your hands are in a steeple position when your finger tips are touching together. It's a classic look for chess players and supervillains, but it can also benefit you.

"If you don't, the interviewer will assume you are either insecure, don't have an appropriate answer for the question being asked, or are being deceptive. Does that mean it's true? No, but perception is everything in a job interview."

"It also sets off the mirror neurons in your listener, instructing them to smile back. Without the smile, an individual is often seen as grim or aloof," she explained.

This may give the interviewer the impression that you're bored or uninterested in the conversation. Instead, keep your hands on the desk or table, and don't fidget.

In their book "Crazy Good Interviewing," John B. Molidor, Ph.D., and Barbara Parus suggest showing your palms during an interview — since the gesture indicates sincerity — or pressing the fingertips of your hands together to form a church steeple. which displays confidence, reports Business Insider's Shana Lebowitz.

"People don't realize that the job interview begins in the waiting room, but it does. So don't slouch in the chair in the reception area," she advised. "In order to be perceived as confident, you must sit or stand tall, with your neck elongated, ears and shoulders aligned, and chest slightly protruding."

This position changes the chemicals in our brain to make us feel stronger and more confident, and it gives the outward appearance of credibility, strength, and vitality, she explained.

Playing with your hair, touching your face, or any other kind of fidgeting can be a major distraction for your interviewer. It also demonstrates a lack of power, said Reiman.

This gesture will tell the interviewer you're not comfortable or you're closed off.

"When we touch our faces or hair, it is because we need self soothing,"Reiman explained.

Is that the message you want to send to your interviewer

A weak handshake may tell the interviewer that you're nervous, shy, and that you lack confidence, explains Colin Shaw, CEO of Beyond Philosophy, a customer experience consultancy, in a LinkedIn post.

Ideally, your handshake should be firm, but not overbearing. "The secret to a great handshake is palm-to-palm contact," Wood told Business Insider. You want to slide your hand down into the web of theirs, and make palm-to-palm contact. Lock thumbs, and apply an equal amount of pressure.

"It's okay to use your hands to illustrate a few important points," writes Lebowitz. "In fact, research suggests that staying too still can give the impression of coldness.

"But relying too much on hand gestures can be distracting, according to Molidor and Parus."

She says you should remember you're in a job interview, not a theater audition.

People tend to show their dominating personality by gripping the interviewer's hand and palming it down, but this tells the interviewer that you need to feel powerful, Reiman explained. "Instead, the handshake should be more natural: thumbs in the upward position and two to three pumps up and down."

As the applicant, you should always wait for the interviewer to extend their hand first, she added.
